Hello, according to the information provided by you, the root cause is that the battery voltage is too low or invalid.
1.On the NMS, manually issue the configuration performed 30 minutes before the power-off.
2.Check whether the jumper cap is correctly placed over the battery jumper. If it is, check the jumper setting of the battery on the system control board. If the setting disables the battery from providing power, change the setting to ensure that the battery provides power to the system control board.
3.If the alarm persists, use a multimeter to measure the battery voltage. If the voltage is lower than 3 V, the battery is out of work. The board must be replaced. Replace the faulty board.
